Review on 🌡️ ORIA Wireless Refrigerator Thermometer with Indoor Outdoor Sensors - Audible Alarm, Min Max Record, Temperature Display for Home, Restaurants, Bars by Sara Wells

This is great to monitor your freezer and fridge, I had some problems so I kept an eye on it. Be sure to use lithium batteries to protect against cold and place the sensors in an open area where air can bypass them and place the sensor at mid-depth or towards the front of the shelf for a better reading. This allows you to set high and low values. for signaling on each section. The alarm clock is also quite loud. Has a trend line so you know if it's getting colder or warmer. It has a strong magnetic base or can be wall mounted. I plan to get one for my camper too.
